Aqualine GPN-150-40 Galvanized Steel Nipple 1.5x4 in Sch 40

Product Description

The AQUALINE GPN-150-40 is a Schedule 40 galvanized steel pipe nipple sized at 1.5 inches in diameter and 4 inches in length. It provides a short, threaded connection between pipe fittings, valves, and equipment in water supply, plumbing, and light industrial piping systems. The hot-dip galvanized coating protects against corrosion in wet and exposed environments. Both ends are threaded for standard NPT connections. Plumbers and pipefitters install this nipple in a wide range of domestic and commercial applications where a reliable, code-compliant steel fitting is required.

This nipple is suited for residential and commercial plumbing installations, water distribution systems, and general-purpose pipe assemblies. Its Schedule 40 wall thickness meets common pressure and flow requirements for cold and hot water lines. The 1.5-inch nominal size fits standard 1.5-inch NPT threaded fittings and valves used across plumbing and HVAC hydronic systems.

Key Features

• Galvanized steel construction provides corrosion resistance in wet environments
• 1.5-inch nominal diameter with NPT threads on both ends

Compatibility

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off and depressurize the water supply before threading or removing any fittings. Apply thread sealant tape or pipe dope to NPT threads before assembly. Do not overtighten threaded connections, as this can crack fittings or distort threads.
